Sediments, Haze and Various Cloud Phenomena Near Yangtze River Mouth, China

The Yangtze River empties a thick load of sediments into the waters of the Yellow Sea, tinging them gold and making apparent the reason for the sea’s name. To the northwest, haze hangs over the plain near Beijing and over the Bohai Sea. East of the rivermouth, two other kinds of atmospheric phenomena can be observed: wave clouds (the straight, parallel lines of clouds) and van Kármán vortex streets (the clouds organized into two rows of spirals).
